Description
Technical field
The utility model relates to elevator electrical installation, relates in particular to a kind of energy-conserving elevator supply unit.
Background technology
Along with social development, civilian and industrial elevator increasing year by year.Its topmost purposes of elevator is exactly manned and loading, and due to all the more general of skyscraper, its power consumption is also very surprising.In the operational process of elevator, when the weight of lift car is greater than elevator counterweight, when elevator moves, can " electricity consumption "; And the weight of working as lift car is less than elevator counterweight, when elevator moves, can " generate electricity ", the electric energy that these elevators self produce at present, can only consume in braking resistor in the mode of heating by brake unit, cause on the one hand the waste of electric energy, consume again on the other hand civil power.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of energy-conserving elevator supply unit.
Energy-conserving elevator supply unit of the present utility model, formed by electrical source exchange module, storage battery, solar energy photovoltaic panel, chopper, voltage transformer and rectifier I, described solar energy photovoltaic panel is connected to storage battery through rectifier II circuit, described electrical source exchange module is provided with two input ends, one be connected with civil power, another is connected with storage battery through inverter, the mouth of electrical source exchange module i.e. the first mouth is connected with elevator frequency converter, and control module I is all connected with storage battery with inverter, electrical source exchange module; The input end of chopper is connected with elevator frequency converter circuit, its mouth connection transformer and rectifier I successively, and the mouth of rectifier I is the second mouth.
As further improvement of the utility model, described chopper is connected with control module II circuit.
Energy-conserving elevator supply unit of the present utility model, utilize on the one hand solar power, save the consumption of civil power, the electric energy conversion producing during on the one hand by elevator generator operation is can be for the direct current (DC) of other equipment utilizations, so not only save the power consumption of elevator main body, also for other consumers provide electric energy, reached energy-conservation object from two aspects.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, energy-conserving elevator supply unit of the present utility model, by electrical source exchange module 1, storage battery 2, solar energy photovoltaic panel 3, chopper 4, voltage transformer 5 and rectifier I 6 form, described solar energy photovoltaic panel 3 is connected to storage battery 2 through rectifier II 7 circuit, described electrical source exchange module 1 is provided with two input ends, one is connected with civil power, another is connected with storage battery 2 through inverter 8, the mouth of electrical source exchange module 1 i.e. the first mouth 9 is connected with elevator frequency converter 10, control module I 13 and inverter 8, electrical source exchange module 1 is all connected with storage battery 2, the input end of chopper 4 is connected with elevator frequency converter 10 circuit, its mouth connection transformer 5 and rectifier I 6 successively, and the mouth of rectifier I 6 is the second mouth 11.Described chopper 4 is connected with control module II 12 circuit.The voltage of its first mouth 9 and the second mouth 11 is respectively AC220V and DC24V.In this device, elevator frequency converter 10 is also connected with brake module and braking resistor, and in the time that elevator electricity can all be utilized, it consumes by brake module and braking resistor heating.
Solar energy photovoltaic panel 3 converts solar energy into electrical energy, and charges for storage battery 2 through rectifier II 7, and in the time that storage battery 2 is full of, control module I starts inverter 8, and electrical source exchange module 1 is switched to storage battery power supply state, is now motor power supply by storage battery; When the electric weight of storage battery 2 is lower than 40% time, control module I switches to mains-supplied state, and now storage battery 2 charges, civil power is motor power supply.
In the time that the weight of lift car is greater than elevator counterweight, the electric energy that utilizes the first mouth of the present utility model to provide, by the rectification module of frequency converter inside, motor obtains required input voltage from the DC bus of frequency converter; In the time that the weight of lift car is less than elevator counterweight, while utilizing generator operation, be created in the feedback electric energy on frequency changer direct current bus, through chopper 4, voltage transformer 5 and rectifier 6, for other low-voltage equipments provide required input voltage as floor display panel, sedan-chair top board etc.Chopper 4 utilizes control module II 12 to determine the output voltage of the second mouth 11.
